Version 4.12.3 Version 4.12.3
============== ==============
- Alpha support for polymorphism.
- SMTLIB3-ish, C, Python
It adds the new command `(declare-type-var A)` that declares a symbol (in this case `A`) globally as a polymorphic type variable.
The C API contains a new function `Z3_mk_type_variable` and a new enumeration case `Z3_TYPE_VAR` as a kind associated with sorts.
All occurrences of `A` are treated as type variables. A function declaration whose signature uses `A` is treated as a shorthand
for declarations of all functions that use instances of `A`.
Assertions that use type variables are shorthands for assertions covering all instantiations.
- Various (ongoing) performance fixes and improvements to smt.arith.solver=6
- A working version of solver.proof.trim=true option. Proofs logs created when using sat.smt=true may be trimmed by running z3
on the generated proof log using the option solver.proof.trim=true.
